The operation of the vehicle opening / closing window operating mechanism having the above-described structure will be described. In order to prevent the temperature inside the passenger compartment from becoming high when the vehicle is stopped under the scorching sun in the summer and the passenger leaves the vehicle, for example, a manual switch 25
By inclining the sunroof main body 15 by performing the above operation, the opening 14 is slightly opened, and the engine is stopped.

Before and after the engine is stopped, the first lever 3 of the temperature detection switch unit 26 in which the occupant was in the standby state
1 is slid to the other end of the unit cylinder 30. Then, as shown in FIG. 9, the revolver 47 causes the bias spring 48 via the shape memory alloy spring 33, the second lever 34, and the pushing spacer 46 by this slide.
Is moved to the other end side of the unit cylinder 30 while being contracted. At this time, the revolver 47 has the convex portion 57.
The pushing spacer 46 moves the first convex portion 51 in the first guide groove 38 of the cylinder guide 37, and finally the convex portion 57 of the revolver 47 moves to a position where the convex portion 57 comes out of the first guide groove 38.

Next, the occupant moves the second lever 34 toward the first lever 31 while inserting the connecting rod 32 into the through hole 34b. Then, as shown in FIG. 10, the biasing force of the shape memory alloy spring 33 introduced into the revolver 47 is released, and basically only the biasing force of the bias spring 48 is introduced into the revolver 47 (at this time, the pushing force is applied). The spacer 46 is supported by the connecting rod 32). As a result, the inclined surface 58 of the convex portion 57 of the revolver 47 moves along the first tip inclined surface 54 of the first convex portion 51 of the extrusion spacer 46 and the first guide inclined surface 41 of the cylinder guide 37. As shown in FIG. 11, the revolver 47 rotates, and the convex portion 57 is on the first guide inclined surface 41 of the cylinder guide 37 and abuts on the stepped portion 43 to stop the rotation further. Become. The rotation position of the revolver 47 at this time is referred to as a first rotation position. By the movement of the second lever 34, the first lever 31 also moves in the return direction and comes into contact with the first trigger 35 and stops.

At this time, if the temperature of the temperature detection switch unit 26 is equal to or lower than the expansion / contraction boundary value, the shape memory alloy spring 33 is in the contracted state and the convex portion 57 of the revolver 47 is present, as shown in FIG. Is on the first guide inclined surface 41 of the cylinder guide 37 and is in contact with the step portion 43. Then, after that, the temperature detection switch unit 26
When the temperature of the shape memory alloy spring 33 exceeds the expansion / contraction boundary value due to the increase in the vehicle compartment temperature, the shape memory alloy spring 33 is in an expanded state as shown in FIG. 12, and the urging force of the shape memory alloy spring 33 causes the second lever 34 and the extrusion spacer. While the revolver 47 contracts the bias spring 48 via 46, the unit cylinder 30
The convex portion 57 of the revolver 47 moves to the other end side of the above until the step portion 43 is crossed. In this state, the rotation of the revolver 47 is restricted by the balance between the biasing force of the shape memory alloy spring 33 and the repulsive force of the bias spring 48.

On the other hand, the second lever 3 shown in FIGS.
When the temperature of the shape memory alloy spring 33 of the temperature detection switch unit 26 has already exceeded the expansion / contraction boundary value during the movement operation of No. 4, the revolver 47 is moved by the movement operation of the second lever 34 as shown in FIG. When the occupant releases the second lever 34 after the cylinder guide 37 comes into contact with the step portion 43 and is restricted from further rotating on the first guide inclined surface 41, the extension state is already reached. By the urging force of the shape memory alloy spring 33 that has been forcibly contracted by the second
Revolver 4 via lever 34 and extrusion spacer 46
7 contracts the bias spring 48 to the other end side of the unit cylinder 30 to the convex portion 57 of the revolver 47.
Moves until it crosses the step 43. In this state, the rotation of the revolver 47 is restricted by the balance between the biasing force of the shape memory alloy spring 33 and the repulsive force of the bias spring 48.

In any of the above cases, when the temperature of the temperature detection switch unit 26 exceeds the expansion / contraction boundary value, the air whose temperature has been lowered by a shower or the like opens the opening 1
When the temperature of the shape memory alloy spring 33 of the temperature detection switch unit 26 drops below the expansion / contraction boundary value, the shape memory alloy spring 33 starts contracting and is introduced into the revolver 47. The biasing force of the shape memory alloy spring 33 is released, and basically only the biasing force of the bias spring 48 is introduced into the revolver 47. As a result, as shown in FIGS. 13 and 14, the inclined surface 58 of the convex portion 57 of the revolver 47 is changed to the second convex portion 5 of the extrusion spacer 46.
The second revolver 47 rotates while moving along the second tip inclined surface 55 of the second cylinder 2 and the second guide inclined surface 42 of the cylinder guide 37, and finally the convex portion 57 of the revolver 47 is located next to the first guide groove 38 of the cylinder guide 37. Rotation is restricted by entering. The rotation position of the revolver 47 at this time is referred to as a second rotation position.

Then, while the revolver 47 is rotating from the first rotation position to the second rotation position in this way, that is, the convex portion 57 of the revolver 47 moves along the second guide inclined surface 42 of the cylinder guide 37. While doing so, the harness contact 44 provided on the second guide inclined surface 42 and the convex portion 57, which is an electric contact, come into contact with each other to be electrically conducted (that is, turned on). With this electrical connection, the control unit 20 reverses the electric motor 22 to close the sunroof body 15. When the shape memory alloy spring 33 contracts, the revolver 47, the pushing spacer 46, the second lever 34, the shape memory alloy spring 33, and the first lever 31 are returned to the standby state by the biasing force of the bias spring 48.

According to the operation mechanism of the vehicle opening / closing window of the present embodiment described above, the vehicle interior 12 is formed by the sunroof body 15.
By keeping the opening 14 between a and the outside 12b of the vehicle open, the temperature rise in the vehicle interior 12a is suppressed. on the other hand,
Rainwater compartment 1 that is concerned about opening the opening 14
Regarding the approach to the inside of 2a, when it starts to rain and the outside air drops, the outside air enters through the opening 14 and detects the temperature in the vicinity of the opening 14.
The temperature detected in 6 decreases, and when this temperature exceeds the expansion / contraction boundary value set in advance and falls below the expansion / contraction boundary value, the control unit 20 causes the electric motor 22 of the sunroof driving unit 19 to move the sunroof body 15 to the sunroof main body 15. Drive the opening 1
By closing 4 the rainwater is prevented from entering the vehicle interior 12a.

In this way, the vehicle interior 12a is constructed with a simple and low cost in which the opening 14 between the vehicle interior 12a and the vehicle exterior 12b is opened by the sunroof body 15 without the need for an expensive solar cell panel. It is possible to suppress an increase in temperature inside the vehicle, and also to prevent rainwater from entering the vehicle interior 12a, which may be a concern by opening the opening 14.

Further, the shape memory alloy spring 3 due to temperature change
Since the temperature detection switch unit 26 that is turned on by the contraction from the extended state of No. 3 drives the sunroof main body 15 by the electric motor 22 of the sunroof driving unit 19 to close the opening 14, the cost is surely reduced. be able to.

Furthermore, with the sunroof body 15 opening the opening 14 between the passenger compartment 12a and the outside 12b, the revolver 47 is moved to a predetermined position by the operation of moving the first lever 31, The second lever 34 to the first
The revolver 47 is formed in the cylinder guide 37 by the biasing force of the bias spring 48 by moving the lever 31 toward the lever 31 and releasing the biasing force of the shape memory alloy spring 33.
It rotates to the first rotation position along the guide inclined surface 41 and stops. Then, when the temperature near the opening 14 exceeds the expansion / contraction boundary value and the shape memory alloy spring 33 is expanded, the revolver 4 is pressed.
7 is in a state in which the rotation is restricted by the biasing force of the shape memory alloy spring 33 and the bias spring 48, and the vehicle interior 12
The state in which the opening 14 between a and the vehicle exterior 12b is opened is maintained. When the rain falls from this state and the temperature drops below a predetermined value and the shape memory alloy spring 33 contracts, the revolver 47 moves along the second guide inclined surface 42 formed on the cylinder guide 37 by the biasing force of the bias spring 48. The harness contact 44 is electrically connected to the projection 57, which is an electrical contact, while being rotated to the second rotation position and rotating from the first rotation position to the second rotation position. The sunroof body 15 is driven to close the opening 14. Therefore, the cost can be surely reduced.

In the above embodiment, when the occupant leaves the vehicle, the opening 14 of the sunroof 11 is slightly opened in order to prevent the passenger compartment 12a from having a high temperature. The case where the opening 14 is automatically closed by the sunroof body 15 even if the occupant is away from the vehicle at the time of lowering has been described as an example. By combining the switches, when the temperature of the shape memory alloy spring 33 exceeds the expansion / contraction boundary value, the opening 14 is automatically opened in the sunroof body 15, and automatically when the temperature of the shape memory alloy spring 33 becomes below the expansion / contraction boundary value. Sunroof body 1
It is also possible to fully open and close so that the opening 14 is closed at step 5.

Further, in order to prevent the temperature inside the vehicle compartment 12a from becoming high, the windows on the side of the vehicle body and the rear portion of the vehicle body are slightly opened, and these windows are automatically closed at the time of a shower or a drop in temperature. Is also good.

As described in detail above, the first aspect of the present invention
According to the vehicle opening / closing window actuation mechanism described above, the temperature rise in the vehicle interior is suppressed by keeping the opening in the open state. On the other hand, regarding the entry of rainwater into the passenger compartment, which is a concern when the opening is opened, when the rain starts and the outside air drops, this outside air enters through the opening and the temperature near the opening is reduced. The temperature detected by the temperature detection unit for detection decreases, and when the temperature falls below the predetermined value from the state where the temperature exceeds the predetermined value, the control unit drives the window body by the window body drive unit. By closing the opening, rainwater is prevented from entering the vehicle interior. As described above, the temperature rise in the vehicle interior can be suppressed by a simple and low-cost configuration in which the window body opens the opening between the vehicle interior and the exterior without requiring an expensive solar cell panel. In addition, by opening the opening, it is possible to prevent rainwater from entering the passenger compartment, which is a concern.

According to the second aspect of the present invention, there is provided a vehicle opening / closing window actuating mechanism, wherein the switch is turned on by the contraction of the shape memory alloy spring from the expanded state due to the temperature change, and the window body is driven by the window body drive section. It is driven to close the opening. Therefore, compared with the conventional technique of driving a fan or an air conditioner by power generation of a solar cell panel built in a sunroof, only the switch of the present invention is added, and the cost can be surely reduced.

According to the vehicle opening / closing window actuating mechanism of the third aspect of the present invention, the rotating member is operated by moving the first lever while the opening between the vehicle compartment and the outside of the vehicle is opened by the window body. Is moved to a predetermined position, the second lever is moved in the direction of the first lever to release the biasing force of the shape memory alloy spring, so that the rotating member is formed in the guide portion by the biasing force of the bias spring. It rotates to the first rotation position along the first inclined surface and stops. When the temperature in the vicinity of the opening exceeds the predetermined value and the shape memory alloy spring is expanded, the rotation member is in a state in which the rotation is restricted by the biasing force of the shape memory alloy spring and the bias spring. The state where the opening between the vehicle and the outside of the vehicle is opened is maintained. When the temperature falls below a predetermined value from this state and the shape memory alloy spring contracts, the rotating member is moved to the second portion formed in the guide portion by the biasing force of the bias spring.
The first rotation position is rotated along the inclined surface to the second rotation position, and the first rotation position is rotated to the second rotation position.
The electrical contact and the second electrical contact are electrically conducted, and the window body driving unit drives the window body to close the opening. Therefore, as compared with the conventional technique of driving a fan or an air conditioner by the power generation of a solar cell panel incorporated in a sunroof, only the switch of the present invention is added, so that the cost can be further reliably reduced. .
